A-INFO waveguides are structures for guiding electromagnetic waves, often called a waveguide transmission line. Our waveguides are low loss transmission lines capable of handling high power with high isolation. Waveguides are available in standard sizes from WR-2300 through WR-2.2, which encompasses frequencies from 0.32 GHz to 500 GHz.

Available waveguide components include waveguide to coax adapters, waveguide horn antennas, waveguide terminations (loads), waveguide sections and bends, plus more. Visit A-INFO's Waveguides page for product details.
